<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<script src="src/cw-charcount.js"></script>

2. Create an input field with maxlength attribute in the document.

<input type="text" name="name" id="name" maxlength="50">

3. Create a character counter next to the input field.

$('input[maxlength]').CWCharCount();

4. Sample CSS to style th character counter.

.cw_count {
  border: 1px solid #b0b1b3;
  color: #666666;

.cw_count_warning {
  border: 1px solid #c10000;
  color: #c10000;
}

5. Available options.

$('input[maxlength]').CWCharCount({

  // This class is applied to the count field on startup and allows you to set the styles needed for it to blend in with your current site styling.
default_class   : 'cw_count', 

// The number of characters remaining before the warning class is added to the count object.
warning_level : 15, 

// This class is added to the count field once the warning level has been reached. It is removed if the character count increases above the warning level.
warning_class : 'cw_count_warning' 

});
